Step 2 Open the front door of the shelf assembly. If the shelf assembly does not have a front door, continue with
Step 4.

The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the
key counterclockwise to unlock the door and clockwise to lock it.
b. Press the door button to release the latch.
c. Swing the door open.
Step 3 (Optional) Remove the front door. If you do not want to remove the door, proceed to Step 4.
a. Detach the ground strap from either the door or the chassis by removing one of the Kepnuts.
b. Place the Kepnut back on the stud after the ground strap is removed to avoid misplacement.
c. Secure the dangling end of the ground strap to the door or chassis with tape.
Step 4 Push the outer side of the handles on the fan-tray assembly to expose the handles.
Step 5 Fold out the retractable handles at the outside edges of the fan tray.
Step 6 Pull the handles and slide the fan-tray assembly one inch (25.4 mm) out of the shelf assembly and wait
until the fans stop.
Step 7 When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.
